how many companies make generic oxycontin. I get the beige ones with a G on top of 164 but its blank on the back. Its not endo, tava, perdue. Its a oxycodone hcl er. I know sometimes the generics are better then the name brand meds because I used to get percocet 5|325 and when I switched insurance I was giving the roxicet which is made by roxane and they helped my pain a lot better than the name brand.
